    摘要： An integrated electrical circuit has at least one memory cell, in which the memory cell is disposed in the region of a surface of a semiconductor substrate. The memory cell contains at least two inverters that are electrically connected to one another. The inverters each contain two complementary MOS transistors having a source, a drain and a channel, the channels of the complementary MOS transistors having different conductivity types. According to the invention, the integrated electrical circuit is constructed in such a way that the inverters are disposed perpendicularly to the surface of the semiconductor substrate. The source, the drain and the channel of the complementary MOS transistors are formed by layers which lie one on top of the other and are disposed in such a way that the complementary MOS transistors are situated one above the other. The invention furthermore relates to a method for fabricating the integrated electrical circuit.

    摘要： A method for the manufacture of a MESFET comprising a gate that is self-aligned both with respect to the source and drain regions as well as with respect to the appertaining metallizations, whereby a first metal layer (21), a first dielectric layer (31), and a first lacquer mask layer are applied following doping of the carrier substrate. A trench producing an outer recess in the doping layer (11) is formed by anisotropic etching. A second dielectric layer is isotropically deposited and is anisotropically re-etched except for spacers (51/52) whereby an inner recess (double recess) is produced in the doping layer and, finally, the gate metal (22) is applied.

    摘要： Memory cell transistors with back-channel isolation are produced without using an SOI substrate. With the word line stack acting as a mask, the semiconductor material is etched on both sides of the world line, first anisotropically and then isotropically to widen the etch hole and form an undercut beneath the gate electrode and at a distance from the ONO storage layer forming the gate dielectric. The undercut is filled, whereby a buried oxide layer of at least 20 nm maximum thickness is formed underneath the channel region. The latter is p-doped at a density of at least 1017 cm−3.
